Firstly, p-methylacetophenone was obtained in the presence of alchlor as the catalyst, and the optimum condition was 4:1:2 in molar ratio for toluene, acetic anhydride and alchlor with yield of 86.2%.

首先，以甲苯和乙酸料，在催化剂三氯化铝存在下合成对甲苯乙酮，并确定甲苯，乙酸和三氯化铝摩尔比4: 1: 2，收率86.2%。

Solid acid alchlor catalyst was prepared from anhydrous aluminium trichloride through liquid solid solvent method,with pretreated bentonite as support.

以无水三氯化铝料,并以处理过膨润土载体,采用液固溶剂法制备固体酸催化剂。
